Welcome in H.C.M.
I have gone through your query regarding pain and hearing loss
in right ear whenever burping is there.
Your symptoms favors that you are having upper respiratory tract
infection may be evident or in sub clinical stage.This type of infections usually puts the eustachian tube in dysfunction which results in pain in ear and loss of hearing.
You should do-
1- C.T.Scan of paranasal sinuses
and stapedial reflexes.
3- Culture and sensitivity of throat swab and sputum for AFB.
4- X-Ray chest.
Till the investigations are going on and diagnosis is awaited you may take-
a- Anti histaminic.
b- Tab Paracetamol
c- Steam inhalation.
d- Antibiotic - this is decided by culture report but till report is awaited you may take any broad spectrum antibiotic.
I hope this will help you.
